Maximum and average demand values
In addition to the measured values listed above, FC610 provides demand values to assist the
operator to carry out energy consumption analysis and achieve increase in energy efficiency.
Demand value is the time-integrated value of the measured values. It is the average value cal-
culated over the demand integration time.
The demand integration time in FC610 are selectable from 2 s, 10 s, 5 min, 8 min, 10 min, 15
min, 20 min, 30 min and 60 mins. The integration time is calculated by the sliding method.
The sliding time interval is 1 second when the integration time is selected as 2 or 10 seconds.
When the integration time is 5,8,10,20,30, 60 minutes, the sliding time interval is 1 minute.
For example, when 2s integration time is selected, the measured values are integrated for a 2
second time window. The sliding time interval is 1 second which means that the demand
value is calculated and updated every second.
Similarly, when 10min integration time is selected, the demand value is calculated for a
10mins period time window. The sliding time interval is 1minute which means that the de-
mand value is calculated and updated every minute.
Maximum demand value is the maximum average value since FC610 is powered up or last reset.
The maximum demand value is resettable through fieldbus only.
